A carton closure apparatus releasably and securely closes a carton having a rectangular bottom, four side walls, two minor top flaps connected to the shorter two walls, and two major top flaps connected to the longer two walls. The apparatus has two parts. The first part is an insert that has a planar surface and a latching member that extends away from and at a right angle to the planar surface. The second part is a socket that has a receiving member for releasably and securely engaging the latching member of the insert. The socket is attached to one of the shorter side walls of the carton at a point along the top edge and equidistant from the adjoining side walls. When the two major top flaps are folded over the two minor top flaps and the insert is placed into the socket with the insert's planar surface extending over a portion of each of the major top flaps, the carton is releasably and securely closed.
